Tanvir Nickel Alloys is a reputable manufacturer and supplier located in Cairo, Egypt, specializing in high-quality Hastelloy Stud Bolts that are engineered for outstanding performance in tough industrial settings. These stud bolts are well-known for their remarkable strength, resistance to corrosion, and durability, even in high-temperature and highly corrosive environments. At Tanvir Nickel Alloys, precision manufacturing and strict compliance with international standards are top priorities, ensuring that customers receive reliable and long-lasting fastening solutions. Commonly found in industries like chemical processing, petrochemicals, marine, and power generation, Hastelloy Stud Bolts provide secure and stable connections, promoting safety, operational efficiency, and long-term performance in demanding applications.
Hastelloy Stud Bolts are primarily made up of nickel (40–65%), along with notable amounts of molybdenum (15–30%), iron, and chromium, plus trace elements like cobalt and tungsten. This unique composition grants them exceptional resistance to both oxidizing and reducing environments, acids, and corrosion caused by chlorides. On the mechanical side, they boast a tensile strength of around 450–750 MPa, yield strength of 200–400 MPa, and an elongation of 30–50%. The alloy also maintains impressive toughness, dimensional stability, and creep resistance, even under high temperatures and harsh operating conditions.
